In this booster

Booked a ryokan with a shared bath? Spotted the ゆ (yu) curtain down a side street? This booster is the water: hot springs, bathhouses, and every rule that guards them. The bath is the one place in Japan where etiquette mistakes are watched most closely — and the place a traveler with three sentences and clean manners is most warmly welcomed.

No new grammar — every sentence here is a frame you already own, wearing new nouns. Mostly Lesson 4’s doko / arimasu, Lesson 7’s permission frame, Lesson 6’s kara / made hours, and Lesson 1’s onegaishimasu. Boosters assume the finished core (Lessons 1–9); take them in any order. (Staying the night wrapped around this bath — the tatami room, the futon, the kaiseki dinner — is the Ryokan booster.)

As always: tap each sentence and listen first, repeat it aloud, then check yourself against the text and meaning that appear. Tap again to listen as often as you like.

Finding the bath

Onsen wa doko desu ka.

onsen — hot spring: mineral water out of the actual earth, and the reason half of rural Japan gets visited. Lesson 4’s doko frame carries it from the front desk to the end of the hallway.

Ofuro wa arimasu ka.

ofuro — the bath, the general word: the tub in your room, the shared one downstairs. Ask this at check-in and follow the pointing hand.

Rotenburo wa arimasu ka.

rotenburo — the open-air bath: outside, under sky, sometimes under snow. The single best word in this booster; ask for it everywhere.

Sentou wa chikai desu ka.

sentou — the neighborhood public bathhouse: city version, no hot spring under it, pure local life. Lesson 6’s chikai does the geography.

Onsen wa nan-ji made desu ka.

Lesson 6’s hours frame, pointed at the water. Ryokan baths often close for cleaning at night and swap sides in the morning — this question saves the disappointment.

Ashiyu wa doko desu ka.

ashiyu — the free public foot bath: shoes off, feet in, at stations and street corners in onsen towns. The zero-commitment version of everything in this booster.

At the door

Two curtains, one kanji each. The bath splits by gender at the door: 男 (otoko — men) and 女 (onna — women), often on a blue and a red noren curtain. These two kanji are the only reading the core lessons will ever ask of you (loanword script has its own skill) — the alternative is a memorable story.

Kore wa otoko desu ka.

otoko — man. When the curtains aren’t color-coded and the kanji hasn’t stuck yet: point and ask. Lesson 2’s very first frame, guarding the very last door.

Onna wa migi desu ka.

onna — woman. With Lesson 6’s migi, it sorts the two doors from a safe distance. (Careful: many ryokan swap the men’s and women’s baths overnight — yesterday’s door may be today’s wrong one.)

Datsuijo wa doko desu ka.

datsuijo — the changing room, between the door and the water. Everything you own stays here — which raises the next question.

Rokkaa wa arimasu ka.

rokkaa — locker, the loanword. Sentou lockers take a coin or a wristband key; ask, and the attendant will mime the rest.

The rules of the water

Taoru wa arimasu ka.

taoru — towel. Ryokan provide them; sentou usually rent or sell them. Ask before undressing, not after.

Taoru, onegaishimasu.

The follow-up to Taoru wa arimasu ka. — Lesson 1’s onegaishimasu, doing what it has always done.

Sekken wa arimasu ka.

sekken — soap. Onsen almost always stock it at the wash stations; old-school sentou may not — this question is the difference between the two.

Shanpuu wa doko desu ka.

shanpuu — shampoo, another loanword you already half-own. Wash-station shelf, usually — but asking beats wandering wet.

Mizugi wa daijoubu desu ka.

mizugi — swimsuit. At a traditional onsen or sentou the answer is always no — nudity is the uniform. But mixed-gender baths and spa-resort pools exist, and there this question earns its keep.

Yu wa atsui desu ne.

yu — hot water: the ゆ on the curtain outside, and the thing itself once you’re in it. With Lesson 9’s ne, this is authentic bath small talk — 42°C water makes philosophers of everyone.

After the bath

Yukata, ii desu ka.

yukata — the cotton robe folded in your ryokan room. The answer is yes — wear it to the bath, to dinner, to the lobby — but Lesson 7’s permission frame asks it politely. (Left side over right; the reverse is for funerals, and someone will quietly fix you.)

Kashikiri-buro wa ikura desu ka.

kashikiri-buro — the private, bookable family bath. The workaround for shyness, tattoos, or a first-timer who wants to learn the ropes alone — usually rented by the hour.

Kashikiri-buro, yoyaku onegaishimasu.

Lesson 7’s reservation move, unchanged: name the thing, add yoyaku onegaishimasu.

Gyuunyuu wa arimasu ka.

gyuunyuu — milk. The post-bath bottle of cold milk, drunk in one go with a hand on your hip, is a sentou institution older than your grandparents. The fridge is by the exit. Participate.

Set piece

Irezumi wa daijoubu desu ka.

irezumi — tattoo. The most important question in this booster: many baths still refuse tattoos (an old yakuza association), others allow small or covered ones. Ask it at the front desk, before paying — memorize it whole and deploy it first. A chotto… answer means no; a kashikiri-buro is often the offered compromise.

Dialog

Checking in at a small onsen ryokan: hours, the tattoo question, a towel. Listen to the whole dialog cold first.

Sumimasen. Onsen wa nan-ji made desu ka. Yoru juu-ji made desu. Irezumi wa daijoubu desu ka. Chiisai irezumi wa daijoubu desu yo. Taoru wa arimasu ka. Hai, arimasu. Ni-hyaku en desu. Ja, taoru, onegaishimasu. Hai, douzo. Arigatou gozaimasu.

Every traveler line is core grammar with this booster’s nouns in the slots — the tattoo answer even came back in Lesson 9’s friendly yo. That’s the whole booster promise, kept.

What they’ll say to you

The two house rules, as a staff member or a wall sign will phrase them. You never say these — catch the keyword (taoru, and the wash-first idea), nod, comply.

Karada o aratte kara, ohairi kudasai. Taoru wa yu ni irenaide kudasai.

The verbs in these (aratte, irenaide) are outside your kit on purpose — you only need to recognize the rule being pointed at, and you’ll already be following it.

Repair drill

Ask about the open-air bath and the front desk may reply with the full timetable — including the overnight men’s/women’s swap — in one keigo breath. You are not expected to parse it.

Sumimasen. Rotenburo wa nan-ji kara desu ka. Rotenburo wa gogo san-ji kara yoru juu-ji made, otoko-yu to onna-yu wa irekae-sei to natte orimasu. Yasashii nihongo de, yukkuri onegaishimasu. San-ji kara desu.

One combined ask — simpler words, slower pace — bought the one fact you needed: an hour you drilled in Lesson 6. The swap-schedule details live on the sign by the door anyway, next to a clock.

How to behave: the laws of the bath

  • Wash first — completely. Sit at a shower stall, soap and rinse head to toe before touching the bath. The bath is for soaking, not washing; entering soapy or unwashed is the one unforgivable move.
  • The small towel never enters the water. Fold it on your head or leave it on the edge. The big towel never leaves the datsuijo. (Long hair obeys the same law — tie it up, out of the water; most front desks keep hair ties if you forgot one.)
  • Naked means naked. No swimsuit at a traditional onsen or sentou — everyone is bare, nobody looks, and the self-consciousness evaporates in about ninety seconds. (Mizugi wa daijoubu desu ka is only for mixed baths and spa pools.)
  • Ask about tattoos before paying. Irezumi wa daijoubu desu ka at the desk. If the answer is chotto…, that’s a no — take it gracefully; a cover sticker or a kashikiri-buro is usually the offered path in.
  • The sauna runs on two more laws. Your small towel (or the mat stacked by the door) goes under you on the bench — bare skin never touches the wood. And before the cold plunge (mizuburo, the small deep tub waiting beside the sauna door), rinse the sweat off first — a scoop from the ladle or a pass under the shower. Sweat never enters shared water: it’s the wash-first law, one room over.

Checkpoint

Your exit exam, out loud. Each line below sets a scene from this booster — say the Japanese before you tap; the tap plays the answer. Check yourself, repeat after the audio matching its pronunciation, rhythm, and speed, and if one won’t come, replay its section. These are this deck’s speaking cards — in Anki they queue up after the listening cards, so you’ll always have heard a line before you’re asked to produce it.
